This invention relates to shutters radiators.

for

An object of the invention is the provision of a device which is simple in construction 5 that it may be readily applied to or removed from a radiator for controlling the flow of cool air through said radiator, the device ing adjustable for varying the quantity of air passing through the radiator.

A further object of the invention is the provision of an adjustable shutter arrangement for controlling the quantity of air p ing through a radiator of an automobile,

ass-

the

shutters being supported and adjusted by a means which is adapted for the ready moval or application of the shutter, to radiator.

This invention will be best underst from a consideration of the following tailed description in connection with the rethe ood decompanying drawings; nevertheless, it is to be; understood that theinvention is not confined to the disclosure being susceptible of such changes and modifications as shall define nomaterial departure from the. salient features of the inventionas expressed inthe pended cla1ms.=

usual crank for turning over the engine A plurality of shutters23, 24 and25 have their adjacent edges overlapping and are maintained in position by means of ,a' cord having two sections26 and 27. The sections of the cord are connected to an elastic member 28 such as a spring and said elastic memher is engaged around the .filling neck 21. An elastic member 29 has one end-engaging a perforation 30 in the lower shutter 25, and the other. end engaged within the opening 22.

It will be/noted that each section of the cord ispassed through similar openings in the shutters-and since these cords pass through openings which are at right angles to the general direction of thecord, theedgesof the openings will exercise a frictional grip on the cord for aiding in maintainingthe shutters .ina predetermined position. The section 26 which extends fron the elastic member, 28 passes a through an opening -31 from the under face otthe shutter 23]"outwardly and over the outerface of said shutter, andafter being received byanotch 32in the lower edge of thenshutter 23, the cord trained over the rear portion of the shutter 24:;and broughtforwardly through an opening 38 in'therupper end ofthecshutter 24 whence it' is carried downwardly and passed readily through a. notch 34 in the; lower end of the shutter 24-andthen disposed over the upperfendof. the shutter'25 and inserted through an. opening 35 ,in the-shutter 25, whence the cord is; carried across-the rear face of said shutter as shown in dotted lines at *36 in Figure-land is then brought forwardly through aqperforation ,37, carried upwardly throughthe notch .38 and inserted 23 andthen trained along the rear face of said shutter after the cord has been passed through an o 41. The free end of the portion 27 a; the cord is connected to the resilient a member 28. Perforations 42 disposed in the adjacent ed es of the various shutters provide f r .7 of a securing means iiesmd for r in maintaining the shutters in position.

The shutters shownanFigs. 1 and 2 are in substantially closed positionand 1t is only nry to release the elast1c member 28 from the filling neck or nipple 21 and move the I: per shutters downwardly to the peeltion, esired. In the open pos1t1on the upper emitter-23 is located outward of shutter 24 whichi'sin contaet'with shutter 25 and outwardly thereof. It will be noted in 131115 case that portionso-f theeerewin be posltioned be- 20 so titat it-is necessary to f'additichal to permit this overhfthe'cord' aha rear of the two upper and Ihai eprovided an extension 66 of the elasticmemb'cr 28 which. has a hook g to provide for theadditional length of coi'diequired for urpose. However,

when the shutters are c osed the elastic ex-- tension 66 is not loyed.

When the hook 67 is released from its position in Fig. 3, the upper end of the cord is secured to the hook 67 thereby lengthenin the elastic member 54 and providing for eek in the cords and 51, which slack is utilized as noted above. 7

Referring to Figs. 5 audit, it will be seen that when the modified form of the invention is applied to a radiator 70 in which the shutter 71 is provided with pairs of perforations 72 and 7 3 to receive the sections 74 of the cord, which has its free ends connected to an elastic member 75 engaging around a filling nipple 76. The cord is brought downwardl over the outer face of the shutter 71 over the upper edge of a shutter 77, through perforations 78 and then downwardly at the rear face of theshutter 77 and outwardly through per- 81 for. maintaining the shutter in position.

The shutter 71 is adapted to be moved downwardly and be located at the rear of the shutter 77- when it is desired to supply more air tothe radiator as illustrated in another form shown in Fig. 11. The threading of the sections 74 of the cord through the restricted perforations in the shutters will aid in maintaining the shutters in any position desired.

A further modified form of the invention is shown in Figs. 7 and Band in which the threading of the sections'74 of the cord is varied so that when the shutter'82 is moved downwardly, as shown in Fig. 8, a portion 83 of the cord will be received within the shutter 82 with the portion 84 of the cord being located between the shutter 82 and the shutter 85. The lower end of shutter 85 is connected by means of a hook 86 to an opening 87 through which the crank is inserted for turning over the engine. The shutter 82 is provided with perforations 88 through which the cord is inserted and shutter 85 is provided with==perforations 89 and 89 to receive the cord.

a A still'further modified am of the invenlid closed. Shutter 90 is supported on the out- 7 or face of the radiator 91 by means of a cord 92 engaged atits upper I ends to an elastic member 93' engaging a filling nipple 94. The

list

cord is inserted through perforations 95, the W shutter 90 and then downwardly and passed through perforations 96 infshutter 97. The

"lower end ofthe shutter is provided with perforations 98 which receive hooks 99 for conformishown irrFigs. 6 to 8, inclusive, the up per shutter 92 is adapted to be moved to the rear of the shutter 97 when it is desired to have more air pass through the radiator.

When desired a cord 103 is trained around the rear face of the radiator and has its ends connected to perforations 102 in the shutter 77 by means of elastic members 101, Fig. 5. Such a cord and elastic member may be employed with each shutter in all the forms.

I claim I 1. A shutter arrangement for radiators of automobiles comprising a plurality of shutters having perforations, a cord threaded through the perforations and permitting adjustment of the shutter, elastic means for connecting the shutter to a radiator, and certain of the shutters having notches to provide for a variable adjustment of the shutters rela-' tive to each other, and for releasing the lower end of the shutters from the cord.

2. A shutter arrangement for radiators of automobiles comprising a plurality of shutters provided with perforations and slidably mounted, cords threaded through the perforations to permit sliding of'the shutters in predetermined position, resilient means for supporting the shutters on the radiator, the edges of the perforation frictionally engaging the cords for aiding in retaining the shutters in position when adjusted, the lower edges of the shutters having notches to receive the cords for aiding in retaining the shutters in position and permitting ready overlapping of the lower ends of the shutters on the upper end of an adjacent shutter.

3. A shutter arrangement for radiators of automobiles comprising a plurality of shutters provided with perforations and slidably mounted, cords threaded through the perforations to permit sliding of the shutters in predetermined position, resilient means for supporting the shutters on the radiator, certain of the shutters having notches in the lower edges thereof to receive the cords for aiding in retaining the shutters in a predetermined position and to permit freedom of adjustment of said shutters.
